2.2.1. Binary gas separation
Fig. 2b illustrates the operation of a membrane module with
perfect mixing. Weller and Steiner first derived the results for
binary gas separations with perfect mixing. While they did not
express their results in terms of stage cut (Wang et al., 2002), the
stage cut parameter was introduced later (Seader and Henley,
2006).
The overall mass balance is given by:
